Synthesis and characterization of alumina fibers using solution blow spinning

Abstract

This work shows the successful production of alumina nanofibers after thermal treatment of solution blow spun hybrid fibers. These nanofibers were converted into γ-Al2O3 and α-Al2O3 after the thermal treatment in air between 500 to 1200 °C. The X-ray diffraction patterns presented all the characteristics of the γ and α phases of alumina. In addition, the scanning electron micrographs showed alumina nanofiber diameters varying between 200 and 270 nm for different temperatures. The results demonstrated that the solution blowing spinning method is efficient to produce alumina nanofibers.

Solution Blow Spinning (SBS): A Promising Spinning System for Submicron/Nanofibre Production

“…SBS provides safe working conditions during the spinning operation [37]. Santos et al also reported that the SBS method is suitable for producing alumina nanofibres at a low cost with reproducibility [72]. Besides, the airbrushing SBS can "paint" nanofibres on any target, while ES needs an electrically conductive target [13].…”

Ceramic Nanofiber Materials for Wound Healing and Bone Regeneration: A Brief Review

“…Furthermore, nanofibers with different and complex morphology, such as a porous, hollow, or core-shell structure, can be produced with these methods [ 39 , 51 ], expanding the use of these ceramic nanofibers in biomedical applications. Among the materials produced by these techniques, titania, calcium phosphate, alumina, zirconia, calcium silicate, silica, and bioactive glasses can be cited [ 23 , 45 , 48 , 50 , 52 , 53 , 54 , 55 , 56 , 57 ].…”
